Veeder-Root's 1205 Series is the most popular counter in the world, and sets the standard for rugged totalizing counters. It comes available in base mount/knob reset, panel mount/rotary reset, and panel mount/lock & key reset models.  Wide temperature variations don’t upset its thermo-stable wheels and pinions. Severe voltage transients will not damage its direct AC coil, so external surge protection is not required. Duty cycles that result in continuous coil energization won’t degrade its life or performance
